In this letter, a broadband, low-profile, hybrid water antenna is proposed. The hybrid structure combines the resonance of the dielectric resonator (DR) and the resonance of the monopole together to cover the required frequency band. The unique features of the water DR are transparency, reconfigurability, and liquidity, which allows complex structures (including the antenna feeding line) to be placed...
A full wave field-circuit co-simulation method is employed to characterise the time domain behaviour of the Marx generator. Radiation and conduction effects are fully considered. Results from the co-simulation and the circuit simulation are compared; it can be found that the field-circuit co-simulation provides complete information of the system which includes the radiation effect and the mutual coupling...
We propose and develop a nanoprobe-based technique for characterizing femtosecond laser pulses. A preliminary demonstration based on the measurement of the interferometric autocorrelation trace through two-photon fluorescence from a nonlinear nanoprobe is reported.
Two dimensional principal component analysis (2DPCA) extracts the global feature of human face, but the local feature is very important to face recognition. In this paper, adaptively weighted 2DPCA based on local feature is proposed. It combines above approaches through separating original images into multi-blocks. Firstly, the face image is separated into three independent sub-blocks according to...
